Neat!! I like your approach (internal bead physics for modeling of observed phenomena) and see no reason why it couldn't be incorporated into OpenCog, actually.
Also, it seems possible that the same bead physics software library could be used both inside a CogDevWorld, and inside an AI's "internal simulation world" Ben On Sun, Jan 11, 2009 at 4:45 AM, Benjamin Johnston <johns...@it.uts.edu.au> wrote: > Hi Ben, > > I've been looking at the same problem from a different angle... rather than > searching for simplified artificial worlds for an agent to live in, I've > been searching for models of the world to be used directly for reasoning > (i.e., the internal world for an agent situated in the real world). > > > I'll be interested to see what you do with CogDevWorld, however you may be > interested in some of the specifics of my approach: > > > I take the approach that *everything* should be "beads".
